How many solutions are there? Count all transpositions separately.



*For those who don't know, the rules of this game are that you have to fill a 9x9 grid with the numbers 1-9 s.t. every row, column, and 3x3 subgrid contain each number 1-9 exactly once. (The puzzlemaker fills the grid enough so that there's a unique solution for the given info and you have to complete it.)

Well, yeah. But it's no fun to just link to the answer.
I was hoping to get some folks working on it. I was pretty sure it required a programming approach, but was enjoying playing with it here and there and trying to get somewhere. I'll check that site out now.
